Biber's (1988) register features for the British National Corpus
Description
This data set contains a table of the relative frequencies (per 1000 words) of 65 linguistic features (Biber 1988, 1995) for each text document in the British National Corpus (Aston & Burnard 1998).
Biber (1988) introduced these features for the purpose of a multidimensional register analysis. Variables in the data set are numbered according to Biber's list (see e.g. Biber 1995, 95f).
Feature frequencies were automatically extracted from the British National Corpus using query patterns based on part-of-speech tags (Gasthaus 2007). Note that features 60 and 65 had to be omitted because they cannot be identified with sufficient accuracy by the automatic methods. For further information on the extraction methodology, see Gasthaus (2007, 20-21). The original data set and the Python scripts used for feature extraction are available from https://portal.ikw.uni-osnabrueck.de/~CL/download/BSc_Gasthaus2007/; the version included here contains some bug fixes.
Usage
BNCbiber
Format
A numeric matrix with 4048 rows and 65 columns, specifying the relative frequencies
(per 1000 words) of 65 linguistic features. Documents are listed in the same order
as the metadata in BNCmeta and rows are labelled with text IDs, so it
is straightforward to combine the two data sets.
